FEED-GAGE FOR PBINTING-PRESSES.

Specification of Letters Patent.

Patented Sept. 23, 191

Application filed March 1, 1912. Serial No. 680,787.

.l.)oylestown, in the county of Bucks and EBtate of Pennsylvania, haveinvented certain new and useful Improvements in Feed- Gages forPrinting-Presses, of which the following is a specification.

My in' provements relate 'to means for positioning upon the tympan thesheets to be printed which are held thereon in such position, and myleading object is to provide simple and inexpensive means whereby suchgages can be set readily and the sheets automatically placed in thedesired position with uniform accijiracy while avoiding the usualinterference with printing close to the edges of the sheets.

The characteristic features of my improvements are disclosed in thefollowing description and the accompanying drawings in illustrationthereof.

In the drawings, Figure 1 is a plan view of a tympan having myimprovements in gages applied thereto; Fig. 2 is a sectional view takenon the line 2-2. of Fig. 1; Fig. 3 isa' perspective view of the cam withits supporting block for shifting the side gage; Fig. i is a plan viewof the inner section of the side gage with a sectional view of means forsecuring it to the tympan bail; Fig. 5 is a sectional view taken on theline 5-5 of Fig. 4; Fig. 6 is a perspective view of the side gage; Fig.7 a top plan view of a section ofthe same with the adjustable bean ingmember thereon; Fig. 8 is an enlarged sectional view taken transverselythrough the adjustable bearing member of the side gage; Fig. 9 is a sideelevation of a bottom gage with its connections shown in section; Fig.10 is a top plan view of a bottom gage and its connections shown partlyin section; and Fig. 11 is a perspective view of a boti tom gage.

The mechanism, as illustrated in the drawings; comprises the usualtympan 1' having'tho bail'2 with the bearings 3 thereon in combinijit onwith the gripper bar 4 havingth'e'journals 5 engaged in the bearings andthe .c ripper shaft 6 connected by a bolt 7 in adjustable relation tothe grip per bar which has a longitudinal slot 4 through which the boltpasses.

In accordance with my improvements, at

block 8, having the tongues 53 and 8" engagcd in the grooves 2 and 2:iorming guides in the bail 2, is providial with the cam surface S, thesocket 8", the screw hole 8, therecess 8, and the slot 8". The sidegage. arm 9 is provided with the bifurcations 1 S) which rest on theblockon opposite sides i ot its socket 8", the recess 9" which registers:with the recess 8, the flange 5) which engages; an end of the block andthe flange t)" which is engaged in the. slot 8. A washer 10 is engagedto the block bythe screw ll (which passes thcrethrough into the hole 8")and clamps the bi'lt'urcations S) thereto. The washer .has the hub 10which is drawn into the socket 8" and the eccentric pin or stud 10'. Thelatter can be drawn through the recesses 9 and 8, to fix the parts 8 and9 to the bail E2, or turned through 180 degrees so as to clear the blockwhile clamping the gage thereto and permitting these parts free mo\'enient on the bail 2. A block 12 is set in the desired position on thebail 2 bymeans of a screw 12. A. spring 1.3, disposed between them, actsupon the block 8 to thrust it from the block '12. The gage arm 5) makesa slight angle with a. line drawn at right angles to the bail guides anda gage clip I l, adjustable on the arm 9, is provided with the hearing14: which is in a plane at right angles to the bail This clipIl-Jlcomprises the lugs or flanges 14-" and H which emln'ace the edgesof the arm 9, through which and the bearing 14' on the lug 14- passes aspring is) acting against the bar to hold the clip in frictionalengagement thereto. lt wlll be understood that by slipping the clip'l-lalong the arm 9 the bearing H is slnil'tcd transversely andconsequently a nice lateral adjustment of the sheet to be printed can beobtained readily without moving the arm. l

The bar 41: has the shoe 16 connected adjustably thereto by means of a.block 17. The block has a tongue 17 which its in the slot 4 of the bar.The bar, block and shoe are fixed together by the bolt 18 which passesthrough them, the shoe being held firmly by the downwardly extendingflanges 16 which engage the block. This shoe, formed by hemling sheetmetal, is provided with a downwardly bent too 16" 'ljori'ning a camhaving an inclined surface which engages the like sin-face of the am' 8when t li the tympan 1 rises in the operation of carrying to the typethe sheet to be printed. The result of the engagement is to shift theblock 8 and arm against the action of the spring 13, by which the cliplt is caused to act through its bearing 14 on the adjacent edge of thesheet a onthe tympan, automatically adjusting such sheet tothe desiredposition with avoidance of the usual amount of care and time necessaryin manually placing such sheets and preventing the inaccuracies whichcommonly obtain in such manual adj ustments. The sheet, which is thusshifted laterally, has its bottom edge supported by the gage fingers 19,made of sheet metal, having the rearwardly extending bifurcations 19 forengaging them in the desired position, the forward downwardly extendingflanges 19 which rest upon the tympan for the purpose of providing abroad bearing for the bottom edge of the sheet to be printed, theaperture 19 for the passage of the narrow upwardly turned tongue 20, andthe notches 19 for the passage of the clasps 20 which frict-ionallyengage the body of the finger to permit the tongue to be set in thedesired position or wholly detached. Blocks 21, provided with thetongues 21 and 21 engaging the guide grooves 2 and 2 of the bail 2, havethe guide fingers 19 fixed thereto, with the faces of the flanges 19parallel to the guide grooves, by the washers 22 having the hubs 22which lie between the bifurcations 19 and extend into sockets 18 and thescrews 28 which pass through the washers into the blocks 21.

It will be understood that the blocks 21 can be slipped along the bail 2and, by loosening the screws 23, the fingers 19 can be adjustedlongitudinally to bring the bear ing faces of the flanges 19 intoregistration with a mark in the line which it is desired that the loweredge of the paper shall occupy on the tympan, whereupon the fingers areclamped to their blocks and the latter are moved along the bail untilthe fingers are in the desired positions. When new a sheet of paper isplaced on the tympan with its lower edge resting upon the flanges 19under the tongues 20 (which guide and hold the sheets) and a side edgeunder the upturned projecting end 15, of the spring 15, such sheet isadjusted to its final and correct position by the lateral movement ofthe gage arm 9 and the clip 14 due to the engagement of the cam 8 withthe cam 16 in the operation which brings the gripper shaft 6 intoengagement with the tympan. Owing to the narrow character of the parts15 and 20, they will lie between lines of type so that printing close tothe edges of the sheet can be effected.
